ELISA method for estimation of equol

Popis výsledku v původním jazyce

Equol is estrogenic isoflavan, which is formed by the action of intestinal microflora from daidzein (an isoflavone) present in different beverages of leguminous origin. The ability of individual subjects to convert daidzein to equol is highly variable. It has been assumed that equol may have higher biological activity than its precursor. High urinary excretion of equol has been suggested to be associated with a reduction in breast cancer risk and the menopause associated osteoporosis. Here we present the development of a competitive enzyme-linked immunosorbent assay (ELISA) method for the determination of equol in human body fluids. Isoflavone conjugates coupled to bovine serum albumin at positions 7-O- and 4´-O- via a carboxymethyl spacer were used asimmunogens. Conjugates of the same haptens with ovalbumin have been synthesized as coating antigens. Assay?s conditions, including concentrations of antisera and coating antigens, were optimized and the effect of reaction time was determ
